Abstract: The apparatus and method for measuring displacement according to the present invention includes a first beam and a second beam. A first reflection structure reflects a first beam to the surface of an object under test; and a second reflection structure reflects a second beam to the surface of the object under test. The reflected first beam and the reflected second beam have an optical path difference. The object under test scatters a scattering beam of gathering the first and second beams. The scattering beam has an interference signal. A photodetector receives the interference signal of the scattering beam. Then an operational unit receives and computes the interference signal for producing a displacement value. By using the first and second reflection structures, the first and second beams split from an incident beam produce an optical path difference. Thereby, the structure of the apparatus for measuring displacement can be simplified.

Abstract: A method for controlling layer changes for an optical disk drive is provided, where a focus of a laserbeam emitted by a pickup head of the optical disk drive is moved from a current data layer of a disk to a target data layer of the disk. First, a position of a collimator lens of the pickup head is adjusted for spherical aberration correction. The objective lens is then lowered to a low position to move the focus of the laserbeam off the surface of the disk. The objective lens is then raised towards the disk. A focusing error signal is generated while the objective lens is being raised. Whether a target S-curve corresponding to the target data layer is present in the focusing error signal is then started to be detected. If the target S-curve is detected, the focus on operation on the target data layer of the disk is successful.

Abstract: The present invention discloses a method for fabricating polymeric wavelength filter, which method for forming gratings patterns on the UV polymer involves three processing steps. First, a gratings pattern is holographically exposed using a two-beam interference pattern on a positive photo-resister film.

This nickel mold on the photo-resister film then can be subsequently used to transfer the final gratings pattern onto a UV cure epoxy polymer. Whereby, a polymer film can be spun coated on the cure epoxy substrate so as to simplify the fabrication process for obtaining a polymer wavelength filter with good aspect ratio of gratings pattern.
